Shut up you lot with your arguing, or take it outside. MrR needs a bit of TLC here.
MrR, this is totally normal. First 6 weeks are very difficult, next 6 weeks are quite difficult, then there is a really low ebb as the sleep deprivation really starts to bite (Frankly, Amnesty International would try to get this banned if a political regime tried it).
Between 3-6 months there is a slight upward curve on the sleep and housekeeping front. By around 6 months lots of babies start sleeping through, and many people are even discussing having another one, unbelievable as it may seem at the moment.
Things we did that worked for us:
Just keep one room nice, let the rest be a mess if necessary. Set up a cosy breastfeeding den in the nice room with snacks, drinks, TV remote, magazines, cushions, pillows or whatever positioned around the most comfy chair.
Eat lots of posh ready meals or get friends to bring some decent food around. You can actually ask people for casseroles and apple pies if they ring up with offers to come to see you, and people are almost always happy to help. Good homecooked food is excellent for sleep deprivation, we found.
Babies can go into the big wide world in the pram after a couple of weeks. Around this time, make sure wife visits hairdresser or beautician for pampering morale boost. Look after baby for an hour in nearby cafe or pub while she does this; have pint, read paper, feel briefly human. This will prevent cabin fever.
Most importantly of all, tell wife she is amazing and beautiful and that you love her, all the more for giving you this gorgeous, gorgeous baby.
